At the basic level, if I could somehow run a cmd and somehow invoke a
"os" install for the existing system, that would be great. IE, if I
had an "image" that could be downloaded to get a complete
refresh/reinstall that's what I'm looking for.

So, starting from the start, how can I get there, without having
access to the system. And I fully recognize that the soln that gets
developed will not be perfection.

So, if you want to get together to discuss. Hell, I'll do pizza!

Why wouldn't you have that drive imaged onto another drive, so that if the first one dies, you can replace it and be up and running quickly? Reinstalling is going to take a while and you have all sorts of unknowns that haven't been figured out. It sounds like a Rube Goldberg contraption that doesn't really meet the first requirement you have, and can't be easily repurposed for other failure cases. So it's a single use kitchen tool that also doesn't work very well. I think you need to rethink your approach.
